I have a MacBook Pro (15-inch Mid 2009), Mac OS X (10.6.8) whose battery has begun to drain relatively quickly.  I get 2 hours out of it if I'm lucky, simply browsing or looking at email.  I need some assistance determining if I need to try to buy a new battery or if something else is causing an issue.  Here is some of the data on my machine:
